package dependencies

Hello to the community and developers of Kolab,

I'm honestly close to despair. I haven't been able to set up a Kolab 
instance for months.

I have been using Kolab community versions successfully for several years.

However, I am currently unable to install it. No matter whether Debian 
10, Debian 11, Ubuntu 22.04, Ubuntu 20.04 or CentOS etc. pp.

In most cases, the package dependencies are not met. Only with Debian 10 
can I start "setup-kolab" at all, but here too I get one error message 
after the other.

What am I doing wrong?

Best regards

Kai Borgman
